If you’re just diving into the world of CBD, we recommend a starting serving size of two to three milligrams. From there, you can work your way up to 100 or even 200 milligrams, after you’ve taken the time to gradually observe how CBD affects your body and mind. Remember, you cannot overdose on CBD, and there are no reported side effects from using high concentrations. And if you’re using CBD pain relief cream for the first time, remember to apply directly to clean, dry skin.
